Do you any sort of license or planning permission to open a cafe in UK? -

I m thinking of opening a coffee shop in an end terraced house - do you need any planning permission if I was not to serve alcohol or change the layout?

You would need A3 planning permission and you will not get it for a residential building.

yes you need planning permission and health and safety would also be involved,no way would it be easy

Yes, ask your council, business link or citizens advice service for help
